Abstract

The SentenceShaperTM is an AAC processing prosthesis that supports spoken language production in aphasia. Prior research comparing narratives produced on and off the system (aided vs. unaided) found that the aided utterances were longer and showed more grammatical structure. Here we show that the “aided effect” also manifests in greater informativeness of messages with functional content. Thirteen unfamiliar listeners used direct magnitude estimation to rate the informativeness of functional narratives produced by five chronic aphasic participants on and off the SentenceShaper. In support of an aided effect, the narratives of four participants were judged more informative in the aided condition.
